HENRY W. MINNEMEYER, 'OF PITTSBURG, PENNSYLVANIA.

I IMPROVEMENT IN BACK-BAND HOOKS.

Specification'forming part of Letters Patent No. 204,910, dated June 18, 1878; application filed May 6, 1878.

panying drawing, forming part of this specification, in which Figure 1 is a face view of a back-band hook embodying my invention. Fig. 2 is a view of the reverse side of the same 5 and Fig. 3 is a sectional view on the line a: m, Fig. 2.

Like letters refer to like parts wherever they occur.

This invention relates to certain improvements in the construction of that class of articles known as back-band hooks, or the combined hook and buckle used to connect backband and trace-chains for the support of the chains of plow and like harness of cheap nature and common use.

It has for its object the cheap construction of a cast-metal hook which shall be readily adjustable on the back-band, and one not liable to become accidentally disengaged when 1n use.

To this end it consists in forming this hookplate with beveled center bar, and a series of projecting points upon the under or reverse side of the outer cross-bar, whereby the backband, of webbing or other suitable material, is

' held securely with the least amount of crimpinto cross-bars a b 0. Of these bars the middle one, b, is formed with a bevel or slope on its interior surface, as at e, and the outer bar, a, is provided with a series of proj ectin g points, f, arranged near the inner edge of the bar,

and projecting from the rear surface at, or

nearly at, right angles. To the broad slotted portion 9 of the plate A the abruptly-curved trace-hook h is secured.

When in use theback-band or webbing B is passed under bars a and c, and over bar 7), the bevel e of bar I) permitting the webbing to assume a short crimp or bend, which brings the band directly and securely against the points f in the rear edge of bar a, and the lower end of the band of webbing or other suitable material will hug the slotted portion g of the plate, and act as a keeper to prevent the escape of the chain from hook h.

This hook can be readily cast without a core, and subsequently rendered malleable, so as to be cheaply and easily produced, will have a neat appearance when finished, and is eifective and durable.

I am aware that a back-band hook having a center bar provided with downwardly and outwardly projecting points has heretofore been devised, and do not herein claim such subject-matter.

Having thus described the nature and advantages of my invention, what I claim, and desire to secure by Letters Patent, is

The back-band hook formed in a single piece, with center beveled bar, a series of points pro ecting from the rear face of the upper bar, and the trace-hook, the whole substantially as and for the purpose specified.

In testimony whereof I, the said HENRY W. MINNEMEYER, have hereunto set my hand.

H. W. MINNEMEYER.
